1ch self-learning eBay relay-board

[ast]

In case somebody wants to have a cheap single channel relay board which is self learning I got ZK1PA working with Tellstick Net (V17).

http://www.ebay.com/itm/201166795643

It has three different modes:
1. relay pulls and immediately releases, this is set by learning a code pressing button once
2. relay pulls when Tellstick Net device is set on and releases when device is set off, this is set by learning a code pressing button twice
3. relay pulls or releases when setting device on (intended for single button remote controls), this is set by learning a code pressing button three times

Pressing button for 5-10 seconds clears the memory.

It seems to learn almost any device type in Tellstick Net, but I got mode 2 to work properly with Ecosavers Self Learning protocol. Most others just turned the relay on but did not release when device was set to off state.

Board requires 12V DC power. The relay is specified as 20A @ 14VDC, 10A 125VAC, 5A 250VAC. However the PCB creepage distances seem too low for 250VAC so I would not use it for mains voltages as it can be potentially unsafe.

I don't have any idea about the range yet, but if it's good enough I plan to use it to contol Eberspächer fuel operated heater in my car

I´ve bought the relay from the link above, and I´ve connected it to my Tellstick.
I wanna connect this relay to a LED-light. I´ve connected a 12v battery to the relay and the LED-light is also 12v.
How do I connect the LED-light to the relay?
I´m sure this is a very beginner-like question when it comes to electronics, so sorry in advance if I should have known this

See picture for further instructions.

1.) Connect the negative (-) from your 12 supply to - on the LED.
2.) Connect positive (+) from your 12 V to the "COM-terminal.
3.) Connect positive (+) from your LED to the NO-terminal.

Thanks for the replay, but it didn´t work.
How can the relay get power without the + and - be connected to the "+12v-"?
I´ve tried different things now, but unfortunately it doesn´t work.
Any suggestions?

Obviously you have to connect +12V and 0 to the relay power connection as well, not only to the lamp

Maybe ask someone with required know-how that could help you locally?

Figured it out now. Had to learn how relay works. What is NO, NC, COM and so on.
Thanks for helping out
